Tar-Ancalimon (Q, pron. [ˌtaraŋˈkalimon], stem Ancalimond-) was the fourteenth King of Númenor. His name meant "Most Bright".

It was during Tar-Ancalimon's reign that the Númenóreans split into two factions: The larger portion called themselves the "King's Men", following the Kings in their growing opposition to the Ban of the Valar. Envious of the Eldar they began to forsake the Elven-tongues. Those who maintained friendship with the Eldar were called the "Faithful"; they continued to revere the Valar.

Despite their rejection of the Elven-tongues, the royal titles were still given in Quenya. This was done out of custom and for fear that breaking the time-honoured usage would create ill-fortune.[1]
